Senior Embedded C++ / Qt Engineer — Zylo3D

Senior Embedded C++ / Qt Engineer — Zylo3D

Zylo3D is looking for a Senior Embedded C++ / Qt Engineer to join the team working on DentPro, the embedded software platform that powers our professional 3D printers.

This is a full-time hybrid role based in Egypt.

Because the role involves direct work with printers, electronics, sensors, motion systems, and other physical hardware, regular on-site work from our office is a permanent part of the position. This is not a remote role.

What you’ll work on

DentPro runs on embedded Linux and controls the complete printer hardware and machine workflow.

You’ll work on areas such as:

• Designing and evolving the C++ architecture of the embedded platform.
• Developing and maintaining Qt/QML application architecture and UI logic.
• Designing clean hardware abstractions that can support different motherboard and hardware revisions.
• Integrating sensors, actuators, heaters, fans, motors, and other hardware components.
• Designing reliable multithreaded and asynchronous systems.
• Working with machine state, safety logic, error handling, and recovery behavior.
• Improving the testability of hardware-dependent software.
• Working with Linux services, networking, deployment, logging, and system-level debugging.
• Reviewing designs and code and contributing to the technical direction of the platform.
• Working closely with our hardware and product engineering teams as new machine capabilities are introduced.

Requirements

We’re looking for someone with:

• Strong modern C++ fundamentals.
• Professional experience with both Qt and QML / QtQuick.
• Strong understanding of Qt application architecture, signals/slots, object lifetime, threading, and C++/QML integration.
• Experience with multithreading, synchronization, object lifetime, and resource ownership.
• Experience designing maintainable interfaces and abstractions.
• Experience with embedded Linux or Linux-based systems.
• Strong debugging and problem-solving skills.
• Ability to take ownership of technical problems that are not fully decomposed or specified.

We expect engineers in this role to be able to understand a problem, identify important assumptions and constraints, propose a sensible design, and explain the trade-offs behind their decisions.

Strong advantages

Experience with any of the following is valuable:

• Raspberry Pi or similar Linux SBCs.
• GPIO, I2C, SPI, UART, CAN, or similar hardware interfaces.
• Sensors, actuators, motors, and motion-control systems.
• Hardware abstraction layers.
• CMake and cross-compilation.
• Linux services / systemd.
• Networking and client-server communication.
• Configuration-driven systems.
• Automated testing of embedded or hardware-dependent software.
• 3D printers, robotics, industrial equipment, medical devices, or other complex physical products.
